Beginners Question ... Logging & Exporting data

Hi,

I was under the impression that the JS2 would cache data at night to be synced to the (Android) phone in the morning.

There are a bunch of threads on this but basically the Bangle stores the info but there is no syncing right now.

If you just want the data it's probably worth just going to https://banglejs.com/apps/?id=health when connected to your Bangle, and downloading all the health data direct from the watch as a CSV file. No need for Gadgetbridge at all.

it contains significantly less data then I expected.

The health app on the Bangle only stores data every 10 minutes. The '3 minute' option is for the heart rate - it'll take 3 HRM samples every 10 minute slot and use the best/average value of HRM readings - but it only stores one reading per 10 minutes.

If you want more than every 10 minutes and more useful data, you'd be better off just using the recorder app on the Bangle: https://banglejs.com/apps/?id=recorder

You can configure that to store all kinds of data, and at whatever interval you want (even down to a second). You can then download that data off the watch in CSV (or other formats)
